Having a problem creating a device upgrade for a RCA RTD258 HTIB. As a test, I've learned some of the buttons from the OEM remote. Playing these back, they work fine. In IR, the buttons all appear to be decoded correctly. The protocol is identified as RCA, Device 12. However, when I create a device upgrade based on this protocol/device, it doesn't work. I was hoping someone could take a look at the IR file and, hopefully, help me understand what's going on.

When I download your file, I get an empty file. Are you sure you loaded it properly?_________________Rob

Anyway, back to your question. I downloaded a file for a RCA RT2500 which shows that most of the functions do indeed use RCA device code 12 (though the inputs use different device codes, which is as expected with RCA).

I think in order for us to totally figure out where you went wrong here, we'd need to see the original IR file with the learned signals in it and the KM or RM upgrade file.

If you look at the upgrade in IR, you've got the same codes assigned to several buttons. For example, both VOL+ and VOL- are programmed with EFC 113, which I don't think is a valid EFC for RCA. I would expect the EFC for VOL+ to be 059 and VOL- to be 067 (both from device 12).

Maybe you should explain what steps you followed to create this upgrade._________________Rob

the remote is likely a URC-1068 (as it has the PIP keys). When attempting to program it, I used the URC-1067 rdf, as that was the closest I could find. Maybe that's the problem?

When the device upgrade didn't work on the Comcast remote, I didn't want to leave my friend w/o the Comcast remote, so I attempted to recreate the device upgrage on a spare 8910 that I have. Apparently, when I switched the remote type in RM, that whacked all of the codes? (Is that plausible? If so, why is that?)

Anyway, you are right, in the original device upgrade (for the URC-1067), VOL+ is 59 and VOL- is 67. That is also what is shown on the Learned Signals tab of the IR file I posted.

Simply changing remotes wouldn't affect the EFCs that you have entered. Are you sure you entered the correct EFCs in the EFC column?

If you created an RM file for this, please post the actual file in the Diagnosis Area and post a link to it, then I'll be able to tell what you did wrong._________________Rob

The RMDU file that you just posted uses the "RCA Combo (Official)" protocol whereas the IR file that you posted uses the standard RCA protocol, so this isn't the exact upgrade file that was used for the IR file you posted._________________Rob

its been a long time since this post was active.... can somebody please provide me with the hex code fro this controller so i can create a "virtual remote" through a phone app i have, ive tried downloading both the files highlighted in this topic however i cannot open them with any of my programs i have for programming these old comcast remotes to do what they werent meant too.

just looked and the remotes are 27 dollars, for a unit i got for free "center channel shorted out, common problem with these units" i just cannot justify paying 27 dollars when i can get a better unit for 100 more dollars then i currently have at walmart

To program a Comcast remote, you will need a JP1 cable, but I'm guessing that you don't have one. Which model of Comcast remote do you have?_________________Rob
